Freelancer Overview

I have hands-on experience working with large datasets and developing AI models, with a strong focus on data preparation and annotation for machine learning projects. Through my roles as a Machine Learning Intern and Graduate Trainee, I have processed and analyzed data for training pre-trained transformers, developed NLP and computer vision models, and implemented advanced document retrieval systems using Retrieval-Augmented Generation (RAG). My academic background in AI and computing has equipped me with deep knowledge of Python, TensorFlow, PyTorch, Keras, and data-centric workflows. I am skilled in designing, testing, and refining machine learning pipelines, and have worked on projects involving sentiment analysis, document classification, and real-world data integration. My experience collaborating with cross-functional teams and my attention to data quality ensure that I can contribute effectively to data labeling and AI training data initiatives.
